Fluid Flow Rate under Hydraulic Impulse Effect on Well Bottom Zone in Oil Reservoir

详细

The solution is presented for the problem on oil percolation in a reservoir at the present and time-varying pressure difference between the injection and production wells. The area of water blocking under capillary pressure in the well bottom zone is determined. The algorithm is proposed for calculating fluid pressure on the well bottom by readings of echo sounder installed at the well mouth. The penetration zone of pressure fluctuations in the reservoir is estimated, and their effect on enhanced well production is shown.
